Container for tooth paste dispenser - has two opposing vertical slotted grooves in casing

摘要

The container is for a paste type material, and has its upper part closed by a piston, whilst its base is provided with an edge projecting out from the cylindrical casing (1). There is an opening in the centre of the base, and the round edge of it projects above the surface. The edge projecting out of the round cylindrical casing (1) has a notch, and the casing itself has two opposing vertical slotted grooves (12, 14). The piston (2) has a cylindrical pin (3) extending upwards, and in its centre has a blind round hole directed upwards. An alternative arrangement is for the round cylindrical casing (1) to be thin-walled without slotted grooves.
